Specification of Letters Patent.

Patented July 16, 1907.

Application filed April 22, 1907. Serial No. 369,627.

To'all whom it may concem:

Be it known that I, HARVEY A. MOORE, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio,

have invented certain new and useful Improvements tion of those parts of my. devices which are more imchannel device, duly supported upon a cross-tie.

, mediately connected to the mid-track channel device,

also of my invention. Fig. 3 is a transverse vertical section of the device shown in Fig. 2,, the said section being taken in the plane of the dotted line 3, 3, of Fig. 2. Fig.4 is a view of an end portion of the mid-track 5 is a vertical section of the ball and socket upholding .the wheels of the car run.

the rod. which connects below with the roller carrying plate, or roller carrier; This section is made in the direction of the length of the car, and in the plane of the dottedline 5 of Fig. 1, but the screw thread of .said rod is left in elevation. Fig. 6 is a top view of the said roller carrier and rollers, and of a spring for ac t'uatingthe said roller carrier under conditions hereinafterlmentio'ned. Fig. 7 is a perspective view of eitherone of the pairs'of rollers, which are present in the roller carrier.

- 1 I will now proceed to describe my invention in detail.

' any suitable or customary manner.

A 'mdicates the dashboard of the car. B, B respectively indicate the usual rails, on which I provide a mid-track channel piece or device 0, which is preferably located at an equal distance from each ofthe rails B. The principal and necessary features of this mid-track piece 0 are that it must have a slot S its upper or top part, that it must have on each side '0; the slot a projection wherewith the roller can engage thepi'ece and thereby hold the car down, and

the end of the slot should open out to readily ream ne roller carrier as it meets this mid-track piece.

The construction of this mid-track piece 0 is Tu: gallows: The piece is a compound one, being made symmetrically alike. Each piece in end lview consists of a. bottom flange (D -extending horizon;

. an outward, was, upright body pag os iaa a ro e flap piece 0. The latter extends inwardly.

This G oi these opposing pieces do not Fig.

touch each other, but are a sufiicient distance apart to form a slot S wide enough to receive the roller carrier. The lower portion G of each of these pieces C 0*, is duly secured in position. Where wooden crossties are present, the lower flange portion 0 is secured to the tie either by fishplates or the like secured in turn to the tie, or directly as shown in the drawing by spikes C C see Figs. 3, 2 and 4.

The roadbedbetween the ties is usuallyarched, being higher in the middle than at the sides, and the surface of the roadbed will usually be on a level with the top of the flanges C, G" of thechannel piece. It is my purpbse to fiic the bottom of this channel piece so that water will not run down through it. To this end, I 10- cate cement'in the bottom portion of this piece 0. The pieces 0 C of the piece C may be vertical, but I prefer them, each one, to incline downward and inward.

Such an inclination contributes toward making. the midchannel device more compact and also makes a narrower and better channel between thelower portions of the vertical pieces (3 ,0 for the locationof the cement 1 of a comparatively thin piece of metal F, adapted to be received in the slot S and to slide therein freely, but yet to nicely and closely fit said slot S. I provide two pairs of rollersG, G. Each of these rollers is connected to the opposite one of its pair by a shaft or shank G And the preferred mode of holding this roller in place,

in the roller carrier, is by. means of this shaft G This shaft G2 is located in a journal bearing F. of the sheet F of the carrier E. This journal bearing F is shown by dotted lines in Fig. 2, and is plainly seen in the sectionizcd Fig. 3. Various constructions for enabling these rollers to be properly inserted in their respective places in the pieceF may be employed, but a preferred convenient and efiicient one is as follows: A hole H is made in the piece F, at a distance above the journal bearing hole F This hole H is of a size large enough to admit either roller G of a pair. From this hole H a slot or opening H extends to the hole F of the journal bearing, and this slot H is wide enough to allow the shank Gr to pass down from the hole H to the hole F and tobe properly located therein. A key K is present. which has an upper part adapted to fit the hole H aforesaid of the piece F, and a shank or portion K adapted to fit the slot H The edge of the hole H and of'the slot H is beveled, and the key K and its shank lower endoi the i in place, it shall form with the rest of the hole F a perfectly circular hole; in other words, a proper bearing for the shank G of a pair oi the rollers G, G.

In practice, the key K, K having been removed, one of apair of rollers G, G is inserted through the hole H until the shank G istherein. This pair of rollers G, G, Gr is now lowered, the shank G passing down through the slot H and finally reaching and resting in the hear,- ing F The key K, --K is now inserted, its .beveled edges fitting the beveled edges of the aperture H, H

The lower end of this key K, K is prevented fromjcoming out of place by the fact that it is between the rollers G, G. The upper end is suitably fastened. A convenient means for such fastening consists of the lugs H extending out and from the: upper part K of the key, and being in contact with the carrier piece F, and a screw H which extends through this lug and is screwed into the carrier piece F. In this way, the compound or double roller G, G, G is securely located in its working location. By withdrawing the screw H", removing the key K, K, and lifting up the said roller G, G, G, and drawing one end of the roller, out through hole 11, it can be readily removed from the carrier piece for re-- pair, orto give place for a new pair of rollers to be located in its stead.

The rollers G, G, and their carrier E are held by a proper support capable of enabling the rollers and their carriers to be elevated or depressed The preferred construction of support is as follows. A rod N is attached to a journal N of the roller carrier E, and can rotate in said bearing. 'On the upper end of the roller carrier E is a bearing piece M. On this ring M the journal N rests. Above the journal N is an annular bearing piece M and the bearing piece M is connected to the bearing piece M by the flanges M Thus the pieces M and M are stationary (in one) with the roller carrier E, and the rod N with its journal N is free to be rotated. This rod carries a screw thread N On the car is a piece which contains afeinale screw P engaging the screw thread N By rotating this rod N by a crank or hand wheel N, this rod and with it the iournal bearing and carrier are elevated or depressed at will.

A convenient mode of lifting the rpller carrier and its rollers out of the way when not needed, and of lowering it when they are to be in use, is as follows: The screw thread P aforementioned as engaging the screw thread N of the rod N is located in a ball I, and the latter is in turn located in a socket R fixed to the car. This socket has a seat R and a cap R held to the seat-R by bolts R By loosening the bolts the cap R can be removed and the ball P and rod N removed. When the ball P and the rod N are replaced, the cap being replaced and secured, holds the ball P in position. The openings R within cap R and the seat R wherethe rod N passes through them, are made larger than the rod, so as to enable the rod N to be inclined forward or backward as desired.

In order to enable the roller carrier and rollers to be lifted up and out of the way automatically, I provide a spring T which forms a part of a connection T between one part of this carrier E and the car. I have shown such a spring fastened directly to the carrier E,-tl1e other end of the spring being connected directly to a chain or other proper ligament connected to the car,

: but the spring T may be located nearer to the car botmid-length of the car, from inclining beyond what is necessary.

The mode in which my invention is operated is as v follows:-The slotted mid-track device is present on all.

hillsides. When a car is descending the hill or is stopped in ascending the hill, the wheels are liable to slip on the rails B, B of the track. As the car approaches the place where the mid-track is, the operator moves the rod N so that it shall bevertical, and if necessary lowers the carrier by turning the rod N in 'the right direction.v

The lower part of the carrier with its roller enters-the scooped out place W in the roadbed, and next the carrier enters the slot S, asillustrated in Figs. 1 and 3. The rollers G, G are now under. the flanges .0", G of the mid-track device. The operator turns the rod N so as to elevate it, and thereby draws the roller carrier up against the flanges O O and draws thecar down so that its wheels bear hard against the rails. When these car wheels are braked, they cannot slip on the track,

upon its wheels rendered stationary by the brake mechanism is prevented.
